Other Site Characteristics

Les Saligues, formations à dominance de boisements hygrophiles, sont caractéristiques des bords de l'Adour, notamment de son cours moyen. Principalement : au développement des gravières de granulats dans les années 70-80, aux déboisements pour l'agriculture ou la plantation de peupliers. Veiller au maintien d'une quantité et d'une qualité de l'eau suffisante au bon fonctionnement de l'écosystème (pollutions diffuses agricoles, ...).

4.2 Quality and importance

Grand fleuve de plaine dont le lit est encore modifié par des crues importantes (dynamique fluviale toujours active), d'où le renouvellement dans le temps et l'espace des différents habitats liés au cours d'eau et la présence d'assez nombreux bras morts. Des forêts de bois dur (Chênaies de l'Adour) sont également intéressantes pour la région. Les habitats terrestres et aquatiques abritent une flore et une faune remarquable et diversifiée. Présence de la Loutre et de la Cistude d'Europe. Les poissons migrateurs réapparaissent suite à un équipement récent des principaux obstacles sur le cours Aquitain de l'Adour (programme de restauration se poursuivant en Midi-Pyrénées). Le Fluteau nagant (Luronium natans) est également présent sur le site.
